AIR-FLUEJREQISTER. I

.S PECIFICATION forming part of Letters Patent No. 257,107, dated April25, 1882.

' .-.\ppli -atihn tlh-d lcbruary fi l, Isa-.2. (NumodrlJ To u-lltohomitmay concern:

, Be it known that I, Ilnxnv A. Tenet, of Dayton, in tl1e county ofMontgomery and State of Ohio, have invented certain newand usefulImprovements in Air-Flue Registers, of which the following is a. full,clear, and exact description.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a perspective view of one of my improved registers, thegratetloor beingshown detached. Fig. 2 is a sectional side elevation ofthe same, the grate-door being shown in place.

The object of this invention is to prevent liquid and solid lilth throwninto the register from entering the llne, aml also to facilitate:

the cleansing of the register.

The invention consists in an air-flue register constructed with aninclined bottom having its inner part curved upward and forward toprevent any liquid or solid from passingfrom the said bottom llltu theair-flue,aback formed of cross-slats arranged with each lower slat alittle in the rear of and at a less inclination than the next upperslat, to prevent anyliquid filth thrown into the register from enteringthe air-flue, and with a removable grate-door providcd with a lock,whereby the register can be readily cleaned also, in the combination,with the register-walls having sockets, ofa removable grate-door havinglugs and a lock, whereby the grate-door can be readily removed and theregister cleansed; and also in the combination, with the inclined bottomof the gratedoor provided with notches in its lower edge, as will behereinafter fully described.

A repres'entsthe register, the side walls of which are vertical and thetop wall horizontal. The bottom B of the register inclines upward fromits forward edge, so that an y fluid thrown into the register will flowout at the front of the said register. The rear part of the bottom B iscurved upward and forward to such apoint that a vertical line drawnthrough the upper edge of the said curved part will fall within the saidourve, so that a fluid thrown against .the rear part of the said bottomwill not flow into the air-flue, but will be guided forward by the saidlCtll" part and will fall back into the register.

The inner side or back of the register is formed of slats C, theends ofwhich are cast in or otherwise securely connected with the side walls ofthe register, and the upper edge of the upper slat is formed solid withor is closely connected to the rear edge of the top wall of the saidregister. Each upper slat is set farther forward than the preceding oneand at a greater inclination, as shown in Fig. 2, so that any liquidthrown into the register and that comes in contact with and flows up thesaid slats will drop from the upper edge'of each upper slat upon theinner side of the next lower slat, and thus tlow back into the register.The slats C overlap each other, and are placed at such a distance apartthat the tingers can be inserted between the slats for convenienco inwashing the said slats when required. With this construction it will beimpossible for liquid or solid filth thrown or pushed into the registerto get into the air-flue.

The registeris secured in place by screws passing through holes 1) inthe side walls of the register and into timbers built in the wall of theroom, so that the register cannotbe 'worked loose and taken outv whenthe gratedoor E is in place. The side flanges, 1", of the front of theregister have rearwardly-projceting flanges (it upon their outer edgesto prevent the oeeupants of the room from forcing anything beneath thesaid flanges F, and thus prying the register loose.

The front of the register is closed by a grate, E, which has lugs Iformed upon one edge to enter sockets J, formed in the side walls of theregister. The grate E is secured in place by a lock, K, the bolt ofwhich shoots into a socket, L, formed in the side wall of the registerA.

The lock K should be so'made that it cannot be picked by the occupantsofthe room, and should be made in skeleton form, so thatit can bereadily cleansed.

In the lower edge of the grate-door E are formed notches M, as shown inFig.1, to allow liquid filth that may be'thrown into the register toflow out freely. With this construction the register can be. readilyopened and cleansed when necessary.

My improvement is especially designed for insane asylums, prisons, andinfirinaries, but can be used with advantage in other places.

Having thus fully described my invention, I claim as new and desire tosecure b v Letters Patent- 1. An air-flue register constructed,substantially as herein shown anddescribed, with an inclined bottomhaving its inner part eurved upward and forward, a slotted back, and are movable grate-door provided with a look, as set forth.

2. In an airdlue register, the back formed of inclined overlappingcross-slats U, arranged with each lower slat a little in the rear of andat a less inclination from the perpendicular than the nextupper slat,substantially as herein shown and described, whereby liquid filth throwninto the register is prevented from entering the ainllue, as set forth.

3. In anairflue register, the bottom B, having a slight upwardinclination, and having its rear part curved upward and forward,substantially as herein shown and described, whereby liquids and solidsarev prevented from passing; from the-said bottom into the air-flue, asset forth.

4. In an air-line register, the combination, with the registerwallshaving sockets J and L, of the removable grate-door E, having lugs 1 anda lock, K, substantially as herein shown and described, whereby thegrate-door can be readily removed and the register cleansed, as setforth.

5. In an airdine register, the combination, with the inclined bottom B,of the grate-door E, provided with the notches M in its bottom edge,substantially as and for the purpose set dorth.
